Sustainable natural dyes with high color strength and binding capability
Developed through fermentation, these natural dyes offer 20-40 times higher color strength than synthetic dyes and bind directly to natural fibers like cotton, wool, and silk. They are sustainable, non-toxic, and versatile for textile and potential hair dye applications.
Overview
Octarine Bio presents a breakthrough in sustainable dye technology with its natural dyes produced through a fermentation-based manufacturing method. These dyes are not only environmentally friendly and non-toxic but also offer significantly higher color strength compared to traditional synthetic dyes—20 to 40 times more intense. This innovation allows the dyes to bind directly to a wide range of natural fibers, including cotton, wool, and silk, providing vibrant colors such as pink, purple, green, and blue. This method offers a sustainable alternative for the textile industry with potential applications in hair dyeing.
Technical specifications
- Fermentation-based production: Utilizes a natural fermentation process to create dyes.
